Researchers have developed a memory device using a two-dimensional layered-structure material, unlocking the possibility of commercializing the next-generation memory device that can be stably operated at a low power.
For a long time, something important has been regularly neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials.
Using sophisticated optical microscopy techniques, engineers demonstrate that sufficient strain in 2D material can yield single-photon emitters, key to quantum technologies and future photonic circuitry.
Researchers have developed a novel noninvasive approach called nano-radiomics that analyzes imaging data to assess changes in the tumor microenvironment that are not detected with conventional imaging methods.
In topological materials, electrons can display behaviour that is fundamentally different from that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached in a real material.
Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect light and turning the reptile's skin a rainbow of colors. Inspired by this, scientists have developed a way to stretch and strain liquid crystals to generate different colors.
Scientists have invented a new tool -- they call it a ''nanocage'' -- that can catch and straighten out molecule-sized tangles of polymers - -whether made of protein or plastic. This tool -- that works a bit like pulling a wad of thread through a needle hole -- opens a new way to create custom materials that have never been made before.
Thin film coatings do more than add color to walls. For example, they can be used as pharmaceutical devices. How these coatings dry can change their properties, which is especially important for films used in drug delivery. Engineering researchers studying the in situ drying behavior of thin film coatings are visualizing particle interactions with groundbreaking precision. Their findings could impact the development of drug delivery technology.

A technologically relevant material for HAMR data memories are thin films of iron-platinum nanograins. An international team has now observed experimentally for the first time how a special spin-lattice interaction in these iron-platinum thin films cancels out the thermal expansion of the crystal lattice.
Researchers have designed and fabricated an ultrasensitive plasmonic biosensor with the integration of atomically thin perovskite nanomaterials on metasurfaces. For that purpose, they used an atomically thin perovskite nanomaterial with high absorption rate, sandwiched between hexagonal boron nitride and graphene layers, which enables the precise tuning of the depth of the plasmonic resonance dip. This biosensor can reach an ultra-high plasmonic sensitivity for detecting small-molecule, low-concentration analytes.
Researchers have developed a method to 'print' a protective coating of copper oxide over the perovskite device. They have shown that only a 3-nanometre thick coating is sufficient to prevent any damage to the perovskite after depositing the transparent top electrode.
Potential materials for future wearable electronics and other motion-powered, energy-harvesting devices.
New insight into the spin behavior in an exotic state of matter puts us closer to next-generation spintronic devices.
Researchers showed that relatively simple structures can support exponential number of magnetic states -- much greater than previously thought -- and demonstrated switching between the states by generating spin currents. The ability to stabilize and control exponential number of discrete magnetic states in a relatively simple structure constitutes a major contribution to spintronics and may pave the way to multi-level magnetic memory with extremely large number of states per cell, be used for neuromorphic computing, and more.
The nanoparticle targets only leukemic cells and therefore would reduce the severe adverse effects of current treatments. The receptor for this nanoparticle is expressed in 20 types of cancer and associated with a poor prognosis, so this drug could open a new therapeutic pathway for other tumors.
Researchers report their success of synthesizing urchin-like nickel nanoparticles by magneto-solvothermal method. Rotated by a magnetic field, the nanoparticles' mechanical force can destroy tumor cells and achieve the same effect as a scalpel.
In an effort to improve large touchscreens, LED light panels and window-mounted infrared solar cells, researchers have made plastic conductive while also making it more transparent.
